To all whom z't may concern.'

Be it known that I, CHARLES H. HOWARD,- a citizenof Athe United States;residin at Sau 11s, in the county of Essexv and tate assachusetts, haveinvented an Improvement in IfaperfReinforcing Machines, of which thefollowing description, in connection with the accompanying drawings, isa specication, like characters on the draw-v ings representing likeparts.

The'invention to be hereinafter described relates to machinesforreinforcing fabrics, and more particularly to such machines forreinforcing paper fabrics or paper stock by the application theretooffreinforcing filaments.

In this general type of machine, the 'ransversel y extending reinforcingfilaments, which may be threads, cords, wires or similar elements, aredrawn from a source of supply by drawing or distending/ means and placedin transverse position relative to the machine frame, or the paper,carrier or-other receiver to` which the filaments are to be transferred.

In my prior application, Serial ,No. 214,910, led February 1, 1918, isshown, described and claimedv carrier means for'J transferring thefilaments distended by the drawing or distending means to the paper orother receiver. The construction is such that the carrier means iselevated'to the plane of the distending laments, takes theilaments fromthe drawing or distending means, lowers to the plane of the receiver,and is then caused to advance with the receiver in unison therewith toapply the filaments thereto. The' filaments are then released by thecarrier means, and the latter returns to a position in readiness to beelevated to take another group of filaments from the drawing ordistending means.l This has been found to be a good,eflicient mechanismfor the purpose, but the delay occasioned by the return movement of thecarrier means to the distending means limits the output of this machine.However, for efiicient operation/ ,it is desirable that the drawing ordistending means and the carrier means lshoiild be heldagainstzrelative'- movement while the carrier means is taking thefilaments from the gripper means in order that the filaments may beretained in uniform, distended relation. v

One of the objects, therefore, of the pres- Sp-ecication of LettersPatent. i

ent invention, is theprovision of a mechanism whereby the carrier meansmay intermlttently take the filaments from the drawing or distendingmeans without relative movement between them, but may continuouslylapply filaments to the receiver. As a consequence, .the capacity of themachine 1s desirably increased.` In carrying vthis feature of theinvention into practical effect, the carrier means may be in the form4of trains of links or members at the sides of themachine, the members'ofeachA of said f trams being provided with fingers or equivalent elementsfor taking and releasing the filaments at the times required. The'membersv of a. train may be detachably connected or coupled together, sothat while the train is continuously driven,- the leading links ormembers vof t e train may be progressively transferred to the rear ofthetrain. Here they may be raised and lowered to take the filaments -frdmthe drawing or distending means, and then they may be caused to overtakeand couple with in train.

n my prior application, i Serial No. 139,475, filed December 29, 1916,is shown, described and claimed hammer actuated cutter means forsevering the filaments from their source of supply after they have beentaken from. the drawing or distending means by the carrier means. objectof the present inventionl is the provlsion of automatic means foroperatingv the hammer actuated cutter means to sever the distendedfilaments vfrom their source of supply at the proper time.

The drawing-in `or distendingvof the filaments transversely of themachine may be shafts 55 and 57 (Fig. 1) mounted in the gripper frame 13adjacent one end thereof,

and the companion shafts 59-and (S1-adjacent the opposite end of saidframe. The several shafts 55, 57,159 and 61 maytbe each provided withscrew or spiral means suchas 63, substantiallythe same as disclosed inmy said prior application. The construction is such that upon rotationof the screw or spiral means, the drawing or distending means at theopposite sides of the machine will be moved toward and from each other Vto draw or distend the reinforcing filaments into transverse relationwith the machine.

The shafts and 57 may have intermeshing gears 65 and 67. fast thereon,they shafts 59 and 61 may have intermeshing gears 69 and 71 fastthereon, and the shafts 57 and 59 may be connected by connecting rodssuch as 73v pivotally joined to counter-balanced cranks 75 fastl on theshafts 57 and 59.

To drive the shafts of the screw or spiral means, a sprocket wheel 77(Fig. 1) may be mounted fast on one end of the shaft 55, and maybeconnected by a sprocket chain 79 with a sprocket wheel 81 fast on themain driving shaft `5.

The screw or spiral means may be connected with the gripper carrierframe 19 by a shoe or slide 83 (Fig. 3) mounted to slide on the upperflange of the I-beam 17, and

having connections for operative engagement with 'the screw or splralmeans, sa1d' connections being shifted at the times required to effectreveiil ofthe-gripper carrer at the times required. lSince theconnections between the slide or shoe and the screw or, spiral means andthe means for shifting the salud are fully shown and described in myprior copending application, Serial Nos. f

157,009 and 214,910, referred to, detailed description thereof in thepresent application is unnecessary. As stated, the present 1nl ventioncontemplates that after the' fila- Vments have been distendedtransversely of the machine by the distending means,l they shall betransferred to the paper to be rein# forced, or other receiver. Inthepresent 1nstance, a web of'paper 85 is led from a suit? able source ofsupply between calender rolls 87 and 89 on shafts suitably supported onthe machine frame. IThe web of paper may have a suitable adhesiveapplied thereto before reaching said rolls, or the web 4of paper4 may bepreviously gummed and dried, in

which event the gummed surface wouldbe moistened before reaching thecalender rolls 87 and 89. Itis alsowithin the purport of g the inventionthat longitudinal filaments' 91 may be placed upon the paper web, sothat when completed, the web shall have received both longitudinal andvtransverse strength- -ening filaments. The invention has also in viewthe superposing. uponthe paper web another web" 93 ofpaperlor othermaterial which may be led from a suitable source of supply to andbetween the rolls '87 and 89.

The means for taking the distended filasecured to a bar 97 seated fin arecess in a' body 99,'and secured thereto by' screws 101 (Fig. 7), saidbody in turn being mounted onl and secured by screws 103 to -a bar ormember 105 having a rack 107. formed on the base thereof. Coperating andalternating with the series of fingers is a series of ,spring fin ers109 or equivalent elements having their lower ends secured Atoa bar 111located beneath the bar 97 for the vseries of fingers 95. Thebar 111rests upon'the top of the, bar 105, and may be held against lateralmovement with-respect to *thebar 97 by a flange 113 adapted toenteragroove llbetween the body 99 and the bar 97,

but the construction is such that the bar 111l may slide longitudinallyrelatively to the,

bar 97 to cause the fingers to take or releaseV thefilaments, as morefully hereinafter described.' l y Preferably, the series of fingers-'95and 109 have Shanks of resilient material andlheads 95L and 109a havingroughened or other suitable faces for receiving the filatops 119 of theheads facilitate entrance of the filaments into saidnotches.

ments 117 (Fig. 6) between them. Beveledl Each link ormember may beprovided with coupling means for detachably connect-v ing the links ormembers to forma train, said coupling means in the present instance,

comprising a pair of resilient hooks 121 setin kerfs in an end of thebar 105- and secured theret o by screws 1215*." A locking recess 123isat the opposite endfof the ybar 105 and has shoulders for engagementwith the .spring hooks l'121. The construction is such -that when onelink is moved toward the other,"coupling hooks 121 of one will snap intothe locking recess 123 of the other link,

and thereby automatically connect the same.

The locking recess 123 is open at the sides so that the coupling hooksv121 may escape therefrom when one link is shifted laterallyrelatively-to the other, as more fully hereinafter described.

Suitable means may be provided for automatically shifting the finger bar111 longitudinally of the finger bar 97 t0 take and release thefilaments at the times required.

To accomplish this, in the present instance, an actuating device isprovided conveniently in the form of an arm 125 (Figs. 6, 7 and 11)located in a recess in a face of the link, and adapted to rock on ascrew 1271secured to the bar 105 of the link. This arm"may have facets129 and 131 adapted to engage an end of a block133 located in saidrecess and secured to the bottom of the finger bar 111 by screws 135.This block is urged toward one or the other of the facets 129 and 131 bya coil) spring 137 having its ends seated in recesses in the block 133and in the bar 105 at one end of the recess.

The construction is such that when the actuating arm 125 is rocked bymeans to be described from its dotted to its full line position shown inFig. 6, the facet 129 having a longer radius than the facet 131 willengage the block 133 and shift the finger bar 111 to close the fingersto take and hold the filaments. When, however, the actuating arm 125 isrocked by means to be described from its full to its dotted lineposition, the shorter radius facet 131 will be opposite the block 133,and the spring 137 will shift the block and finger bar 111 to open thefingers to release the filaments. The actuating arm will normally beheld in its two positions of adjustment by the pressure lof the springactuated block on the facets.

ySuitable means may be provided to guide the links or members in theircircuit of movement in transferring the filaments from the drawing ordistending means tothe paper web or receiver. In the present form of theinvention, this means comprises an outgoing track 139 (Figs. 2 and 7),and an ingoing or return track 141 mounted on the lower frame of themachine at oppo.- site sides thereof. These tracks may conveniently bein the form of grooves, or channels, so that the links may not only besup! ported, but may be guided laterally. The inner walls 143 of theoutward tracks may project upward nearly tothe tops of the fingers forgripping the filaments to prevent lateral flexion of said fingers whileholding the distended filaments under tension.

The outward and return tracks may be separated by a wall 145 (Fig. 2)extending merely a portion of the length of the tracks, leaving atransfer space 147 at the outward end of the tracks, and a transferspace 149 at the inward end ofthe tracks.l The intermediate wall 145 mayhave a tapered end 151 and a tapered end 153 to facilitate lthe transferof the links to and from the outward and inward tracks, as more fullyhereinafter described.

Suitable means may be provided to drive the links or trains of linksalong their tracks/ To this end driving gears 155 (Figsyl, 4 and 13) maybe loosely mounted on the main shaft 5, referred to, 'and Aprojectupward land the driving gears for the return tracks should be rotated inopposite directions. To accomplish this, miter gears 163 (Fig. 13)

and 165 are secured to the driving gears 159 1 and 155 respectively, andmesh with an intermediate bevel -gear 167 loose on a stub shaft 169mounted on a support 171 on the lower frame. The construction is suchthat the driving gears may be driven continuously in opposite directionsto cause the links or trains of links to travel along the outward andreturn tracks as required.

As stated, an important feature of the invention is the provision ofmeans for transferringthe leading links of the train progressively fromthe front to the rear end of the train after the links have deliveredthe filaments to the paper web or receiver. In the present instance, theleading links are transferred one by one from the outward to the returntrack, and are transferred inv that the overalllengths of a group oflinks and the grippers may be varied as desired.

Suitable means may be provided to shift the leading links progressivelyfrom the outward track through the transfer space 147, referred to, tothe returntrack. To accomplish this, in the present instance, a pair ofrocker arms 173 (Figs. 2 and 10) may be mounted on a rock shaft 175mounted in suitable bearings in the lowerframe of the machine.Coperating with these arms is a cam 177 fast on a countershaft 179journaled' in bearings lmounted on the lower frame, said shaft beingdriven Vby a gear 181 (Fig. 2) lfast thereon meshing with a gear 183fast on a shaft 185 journaled in bearings on the machine frame anddriven by a spiral gear 187 fast on the shaft 185 meshing with ,shaft 5,referred to.

, to engage a short follower arm 191 (Fig. 10)

fast on the rock shaft 175, said follower being ressed toward said camby a coil spring 193 aving one end anchored to the lower frame, and theopposite end anchored to an arm 195 on' the rock shaft 175, the movementof. the follower toward the vcam under the action of'said spring beinglimited by an 'adjustable stop 197.'.

`The construction lis such that'the cam 177 will rock the arms 173 fromtheir full to theirl dotted line positions shown in Fig. 10, and therebyshift the'leading link from the outward to the return track. Aftertransferring a link, the rocker arms will be snapped quickly back fromtheir dotted to their full line positions shown in Fig. 10 to be inreadiness to transfer the next link at the leading end of the train. Thetracks may have suitable slots 199 therein to allow the rock arms toproject up through bottoms of the tracks and engage the links. y 1

The means for transferring the groups of links from the return track tothe outward track, in the present instance of the invention, comprisesthree pairs of rock arms 199 (Figs. 2 and 9) fast on a rock shaft 201mounted in suitable bearings on the lower frame. Coperating with thesearms is a cam 203 fast onthe shaft 179, referred to, and adapted toengagea follower arm 205 fast on the rock shaft 201. The'follower isurged toward said cam by a coil spring 207 having one end anchored tothe lower frame, and its opposite end connected to a short arm 209 faston the rock shaft, the movement of the follower toward the 'cam Vbeinglimited by an adjustable stop 211.

The construction is such that rotation of the cam will rock the threepairs of arms 199 fromtheir dotted totheir full line position shown inFig. 9, and 'thereby will shift the group of links from the return4track through the transfer space 149, referred to, to the outward track.The arms 199 may.

project through slots 213 in the bottoms of:

the tracks and engage the links. It will be noted that the cam 17 7referred to, has three Aprojections thereon', whereas, the cam 203 hasonly one projection thereon, and that said cams are rotated atthesamespeed. As

aconsequence, the cam 177 will transfer three links successively fromthe outward to the return track inthesame` time that thev cam 203vtransfers a group of three 'links from the ret-'urn track tothe outwardtrack.

' Since, as stated, the coupling hooks 121 may.

escape from the lookin recesses 123 of the links when a link is shi edlaterally with respect to the otherfthe leading links will beautomatically uncoupled from the'train in -the course of their transferfrom the out.-

I and 3) projecting upward ward to the return tracks.

ybar 215,.

lThe presentinvention contemplates that after the group of linkshas beentransferred l yfrom .the return to the outward track, the Y group oflinks shall be elevated to bring thelr lingers up to the plane Aof thefila ments dstendedby the drawing or distending means, in order thatsaid ngers may v take the distended filaments therefrom. vTo accomplishthis, in the present instance,'an elevator is provided, conveniently inthe form` of a carrier bar 215 (Figs. 3, 5 and 9) in the inward endportions of'V the outward of'yokes 217 projecting through the bottom .ofthe track, and automatically moved up and down at the times required bycam tracks, said ban being connectedV to a 'pair means. .This 'cammean'sfin the present form` Y of the invention, y1s constructed toafford a quick up and down. movement ofthe elevator bar 215, andcomprises an outer'cam 219 (Fig. 16) vhaving a pair of sharply pitchedcamways .221 lreceiving follower rollers 223 (Fig. 17) on studs 225carried v. by the yoke 217. vWithin the outer cam 219.

is 'an inner cam 227 having camways 229 therein receivingfollowerrollers 231 (Fig.

19) on studs 233 secured t0 the outer cam.

The innercam has a post 235 projecting downward through a pinion 237nformed on a boss depending from the outer cam, said "post being securedin a boss 235 (Fig. 3)

- Cooperating with'the pinion 237 is an arcuate' on the lower frame ofthe machine.

yrack 239.(Figs. -16 and 18) on one end of la rock arm` 241 -having ahub 242 loose on a post 243 (Figs. 3,16 and 18) -mounted on thelower frae of the machine. An arm 245 fast on he hub 242 carriesa rollervconfined against oscillatory movement, 'the turning of the outer camwillcause the yoke follower rollers. to .ride quickly to the upper endsof the camways 221, and the turning of the outer cam will cause itsfollower rollers i 231 to ride to the high points of the camways 229 inthe fixed inner cam 4227, thereby lifting the -outer cam simultaneouslywith the rotation thereof. As a consequence the elevator bar 215. isquickly raised. Also, when the rock arm 2414 moves in the oppositeidirection, it will reversely rotatethe outer cam 219 and quickly lower.the elevator It is desirable vided to prevent thejgroup of links fromvshifting laterally outward afterl transfer toy the elevator. Toaccomplishthis, Ain the present instance, the'elevator may beprovidedwith three pairs of lugs 253 (Figs. 2

that 'means' should be profrom the outer 1,30y

edge of the elevator bar. When the elevator is in its lowest position,the upper ends of these lugs will be down out ofthe Y wayof the group oflinks, but o`n the initial upward movement of the elevator bar, the

lugs will be projected upward to engage the sides of the links andprevent outward lateral movement thereof.

As stated, an important feature `of the invention relates to means foradvancing the group of links to cause the same to overtake and couple tothe rear end of the train of links, being continuously advanced alongthe outward track. To accomplish this, a carrier may be provided, conveniently in the form of a bar 255 (Figs. 3, 5 and 9) having a pusherflange 257 at the rear end thereof, as will be noted in Fig. 5. Thiscarrier bar is located in thejinward portion of the outward track abovethe elevator bar 215, and adapted to slide on rollers 259 on suitablepins secured to the sides of the track. To move` the carrier bar forwardand backward along said @rollers, a pin 261 is connected to said bar,and projects downward through an elongated slot .263 (Fig. 5) in theelevator bar, and thence through ashoe 265 adapted to slidein anelongated guide opening 267 (Fig. 5) in the bottom of the track. Saidpin projects thence downward looselythrough a sleeve 269 carried by adoveta'il cross head 271 adapted to slidel in a guide 273 mounted on thelower frame. A follower 275 works in a screw or spiral camway-277 (Figs.2, 5, 9,'

camway 277 shown developed in Fig. 12

has a portion 277a formed to cause the carrier bar to dwell while thespring lingers of the links are elevated to take the filaments from thedrawing or distending means and lowered; hasa pontion 277b tocause thecarrier bar to advance quickly to enable the vgroup of links on thecarrier bar to overtake and couple with the rear'of the train of'continuously lmoving links; and has a portion 277 to cause the carrierbar to retreat slowly after the group of links has been coupled to thetrain to itsv original position in readiness to receive the next group vof links transferred from the return to the outward track.

' The group of three lihksis moving rearward inthe course of itstransfer to the carrier bar, and therefore, it is necessary tp advancesaid 'bar slightly .to compensate for this rearward movement and causethe links to aline -properly with the grippers. Therefore, the cam has aportion 277dl to produce this compensating advance of the carrier bar.The dwell of the carrier bar during the transfer is produced by the camportion 277e.

The rotation of the cam cylinder is prop- 'erly timed with respect tothe transfer of the groupof links by the ratio between the gear 289 andthe pinion l287 for driving the cam cylinder.

Suitable means may be provided for automatically coupling the leadinglinks from the train of links on the outward track to the train of linkscontinuously driven along the return track. To accomplish this, in thepresent instance, a pusher slide 291 (Figs. 1, 2, 4 and 10) may belocated at the outward end of the return track on one end of areciprocatory rod 293 adapted to slide in bearings 295 depending fromthe track, said rod being squared to prevent rotation thereof in saidbearings. This rod is `urged toward the right of Fig. 4 by a coil spring`297 confined between one of the bearings 295 and a liange 299 fast onsaid rod. The slide is urged in the' opposite direction by a face cam301 fast on the shaft 185, referred to, and coperating with a roller 303on a. pin secured to the slide.

The construction is such that in the course of the rotation of the cam301, the spring 297 will shift the slide toward the right of Figs. 2 and4, thereby causing said slide to engage the link which has beentransferred from the outward track to the return track, and advance saidlink to couple the same with the rear end of the train continuouslymoved along the return track.

After the link has been so coupled, the cam will quickly return theslide to its position shown in Figs. 2 and 4.-.. The face cam is formedto present three projections, so that three links will be coupled to thereturning train in the course of one rotation of said' cam.

A device has been described for closin and opening the spring fingers totake and release the filaments at the times required.I Suitable meansmay be provided to automatically rock the arm 125 'of this device. Tothis end said arm is provided with a roller305 'adapted to slide upwardin a recess 307 (Figs. 7 and 9) )in the wall- 143 ofl the outward track,and thence into a vertical groove 309 in a slide 311 adapted toreciprocate in a guide groove 313. Since each link is provided with anactuating arm,

qthree grooves 309 are provided in the slide the slide is connected to alever 315 (Figs. 2 and 5) fulcrumed on apin 317 mounted on the frame,and having a roller working in a 311, as vwill be notedA in Fig. 5. Oneend of-l` group of links has been elevated, andthe v ollers 305 of theactuating arms have entered the grooves 309,- the cam disk 321 willshift 'the slide 311 andj'rock-the actuating arm 125 from its dotted toits full line position shown in Fig. 6, and thereby close lthe springfingers and cause the same to grasp the filaments which have beendistendedby'the drawing or distending means. After the links oftheoutward. traveling train havecarried the filaments to the web ofpaper orreceiver, it is desirable to open the spring fingers to release thefilaments. To accomplish this, a fixed abutment 325 Figs. 6 and 7 may besecured by a bolt 27 to the wall 143 of the outward track in the pathvofthe roller 305 of the actuating arm.

The construction is such that as the links progressively pass said fixedabutment, the

. roller 305 of each will engage the same andv rockthe arm 125 from itsfull to its dotted line position shown in Fig. 6,.` thereby allowing thespring 137 to shift the block 133 and the spring finger'bar 111 to theleft of Fig. 6, and open the spring fingers torelease the filaments. -1

It is desirable to stretch o-r tension the fila: ments somewhat afterthey have been taken from thedrawingor Vdistending means by thespringfingers on the links, and before the filaments are applied to thepaper web tion 329 is an elongated groove 335 formed in the bar 105 ofthe link. An incline 337 at one end of said groove coperates with theincline 331, and( the inner edge 339 ofv the bar 105 coperates with theincline 333.

The, construction is such that as the link moves along the track, theinclines 331-and 333 will simultaneously engage the incline 337 and theedge 339 respectively, and thereby shift the link laterally outwardsomewhat and stretch or .tension the `laments.

The projection 329 is-'of a length such thatthe links `will remainoffset during the porvtionof their transit leading to the paper web orreceiver, and thusthe filaments will be maintained in tensioned'condition until the vfilaments have been applied to the web orreceiver.

Suitable means may be provided for severing the filaments from -theirsource of supply after they have been taken from the 60 ga'ippers by thespring iingers'of the links. This means which may be similar in cer-.tain respects to that shown, described and claimedin my saidapplication, Serial No.

'. 139,475, comprises an anvil 341 .(Figs. 3, 7

and 8)l secured to the top of the body 99 of each. link at a pointsomewhatbeneath the upper ends of the spring ngers of the link.Coperating with this anvil is a cutter 343 (Figs. 3 and 21) which may beof a length corresponding to the length of the anvil of each link, anumber of 4said cutters being provided corresponding tothe number oflinks elevated to the grippers. Each cutter may have a cutting edge' forengagement; with the anvil, and the cutter may be secured to a carrierbar 345 by screws 347 (Figs. 21 and 22) entered through elongatedv slots349 in the cutter, the construction being such that the cutter may besusceptible of more or less movement to seat itself on the anvil andsever all of the filaments thereon. The cutters may be vnormally held upfrom the path of the distended filaments by light coil springs 343a(Fig. 22a) connected to pins 343b on the cutter and pins 343c on the bar345, the upward movement of the cutters relatively to said bar beinglimited,

- by the screws 347 entered through the elongated slots 349 in saidcutters. The carrier bar 345 may be secured to arms 351 fast on a rockshaft 353 journaled in bearings on the gripper carrying frame 19,referred to,

adjacent the side ofthe machine where th filaments are supplied.

Suitable hammer means may be provided for striking the cutters againstthe anvils to sever the filaments, in the present instance, comprisingpins 355, one for each cutter, having heads 357 for engagement with thcupper edges of thecutters, saidpins being mounted in sleeves 359 carriedby brackets 361 secured to the gripper carrier frame 19. The hammer pinsmay be urged downward by coil spring 363 confined between the hammerheads 357 and the lower ends of the sleeves 359. Y y

Suitable means may be provided to rock the vcutter bar arms 351 upwardand push thefhammerpins upward to energize their springs. For thispurpose an arm 365 (Figs.

' 3` and 21) may be mounted fast on the rock los shaft 353, and thedownward rocking of the cutter carrier bar 345 may be limited by theengagement of the headof a screw 367,

tapped in a spur. 369 ortthe arm, with a part of the gripper carrierframe, as will be noted in Fig. 3. Coperating with the arm 365 is aroller 373 on the free end of an arm 375 secured to the gripper carrierframe at .the side of the machine opposite to the gripper carrier frameon which the cutters and' hammers' are mounted.

energize the springs 363.r It will be noted that the cutters are thuslifted shortly before the approaching grippers meet each yterfere withthe taking of the filaments from the supply grippers by the takinggripers.

p The hammers should be held in their elevated energized positions untilthe proper time to release the same to sever the filaments. To this enda locking bar 377 may be provided having key hole s lots 379 (Fig. 20)through which the upper endsof the `hammer pins project, said lockingbar being guided by inturned flanges 381 at the tops of the sleeves 359for the hammer pins. The hammer pins may have circumferential grooves383 (Fig. 22) therein, and the lock bar may be shifted to cause thereduced portions of the key hole slots to receive the circumferentialgrooves 383 and hold the ham- .mer pins in raised position. Then thelock bar may be shifted in the opposite direction to cause the enlargedportions ofthe key hole slots to receive the hammer pins and allow thelatter to be snapped downward by their springs. To shift the lock barto. automatically lock the hammers in their upward positions, a coilspring 385 may be provided having one end anchored to` one of thebrackets 361, `and its opposite end connected to a lug 387 on the lockbar.

After the hammer pins have been locked in their energized positions, thesets of rippers at the supply and taking sides o the machineL willseparate, thereby retracting the arm 375 from the arm 365 and allowingthe cutter carrier bar to lower until limited by the engagement of thestop screw 367 with the gripper carrier frame. This will arrest thecutters at al point such that their light springs 343"L will hold themjustabove the distended filaments where they will be 1n readiness toreceive the impact of the hammers to sever the flaments when the hammersare released by means which will now be described.

To release-the hammers, a cam 389 may be mounted on the shaft 391 and beadapted to engage the lug 393 on the lock bar, the construction beingsuch that in the course of d .the rotation of the cam, it will engagesaid lug and shift thel bar in a direction to re- 'lease the hammer pinsand allow their springs'to impel them downward and cause the cutters tostrike their anvils and sever the filaments from their source of supply.

Suitable means may be provided to rotate the cam 389 and causethe sameto release the hammer pins at the .times required. To

. accomplish this, in the present instance, said `cam` is mounted faston a shaft 395 (Fig. 1)

' 15 at the right epdof Fig. 1. ,The shaft 395 has a sprocket wheel 399fast thereon -con- I nected by a sprocket chain 401 with asprocketwhe'el 403 fast on the shaft 61, re-

ferred to. The construction is such that when the gripper carrier framecarrying the cutting mechanism moves from kits mid position toward theleft of Fig. 3, the lug 393 beneath the lock bar 377 will be broughtinto the plane ofthe cam in position to be .engaged by the projection onsaid cam and the paper bythe rolls 87 and 89 at the delivery end of themachine. As a consequence, the filaments cannot slackenand beuntil theyare pressed into engagement with come irregular, but on the contrary,will be maintained in straight condition so as to afford the maximumreinforcement to the paper and produce a perfect product.

It will be understood thatthe invention is not limited to the specificembodiment shown, but that various deviations may be made therefromwithout departing from the spirit and scope of thel appended claims.
